(no model-I 1 To all whom ifmizycoitciritr Be itknown that I, luous'r WIImIAMHUHs-Q MAN, a citizen of the United States ,.and a resident of Staunton, in the county of. Macoupin 5, andState of Illinois, have invented a new and- Improved Hose, Rod, or Pipe Coupling, of:'

which the following is a full, clear, and exact description.

I ahose, pipe, or 'rod coupling which will be exceedingly simple, durable, and .economic and wherein the parts of' the coupling are capable of-being expeditiously and conveniently brought into locking engagement and as con--- I veniently and rapidlyldisconnected, the coup-.

no exterior projections liable tocatch into articlesfinth'e event the coupling is-draggedover asurface.

. 5 fTheinyention consists in the novel construction and combination of the several parts, as

will be hereinafter fully set forth, and pointed out in the. claims.

. The coupling consists practically of a fef male section A, a male section B, and a locking-ring C, which is carried by the female sec- 50 tion. The male section B consists of-a tubular body 10-of suitable length, which at its The purpose of myinvention isto provide.

"outer end is provided with an enlarged shank portion 11, which shank portion is exteriorly threaded to receive the end of a pipe 12 or the socket of 'a rod when the coupling is to be applied tosuch article; but-when the couplingis to be used in connection with a hose theshank 11 is roughened exteriorly in the customary manner, and the hose is clampedv 'on the shank in the usual way.

At the inner end of the shank 11 an exterior collar'13 is formed on the body 10, and exteriorly of the said body 10, adjacent to the ,col-' Jar-13, a conicalfor inclined projection His produced, the wider end of which faces the plain collar 13 on the said body, whereby an annular groove 15 is obtained .between the two collars 13 and 14, and the bore 16 of the male section, as is'shown in Fig. 2, is uniform in diameter throughout the length of the said section.

a The female section A consists of a body part 17 integral with a reduced. shank 18 at the outer end of the body 17, as isshown in Figs. 2 and 3. This shank 18 is exteriorly threaded whenthe coupling is used iii-connection with a rod or; pipe 19 and is roughened when the coupling is to be used in connection with a hose. In addition to the aforesaid body 17 the female section A comprises an upper and a lower-- jaw a and a, which are hinged, respectively, to the upper and the-lower-portions of thebody 17, as is shown at 20 in the drawings ,.and are adapted to close one upon the other'or to'o'pen from each other,as is shown in Figs-1,2, and 3.

The inner or receiving end of each jaw is provided with anex-terior conical surface 21, as is shown'in Fig. 3, and' an interior correspond: ing surface, 22, as'shown in Fig. 2, and at 9 the extreme inner or receiving end of each jaw ;a .and a segmental rib 23 is produced. Be-

low thesaid rib at the interior of each jaw a segmental flange24 is formed, as is also shown in Fig. 2..

7 The interior conical or inclined faces 22 of the jaws of thefemale section A' are adapted a; slide upon and to engage with the inclined or a conical exterior projection 14 of the body of the male section B when the two sections are brought in coupled position, at which timethe flanges 2 1 of the jaws enter the annular groove between the projections or collars 13 and 14 of the body of the male section, as is also shown in Fig. 2.

The jaws a and a at the back of the inclined v or conical portions 21 are of uniform diameter, and back of a point where the interior conical faces 22 commence the interior diameter of the combined jaws is uniform, and a recess of corresponding diameter is made in the interior of the body 17 of the said female section well to the rear to receive a cushion 27 of elastic material. Otherwise the bore of the body 17 of the female section A is the same as the diameter of the bore 16 of the male section, as is shown in Fig. 2. In the further construction of the jaws a and a registering longitudinal recesses 28 are made in the outer faces of the said jaws at their meetings edges for a-purpose to be hereinafter described.

' At the top and the bottom of the conical exterior surfaces 21 of the jaws a and a longitudinal recesses 29 are produced, which extend practically to the exterior ribs 23, as is shown in Fig. 2. Within each of the said recesses 29 a spring-latch 30 is located, the outer ends 31 whereof are screwed or otherwise secured to the exterior of the ribs 23, being more or less countersunk therein, as is also shown in Fig. 2. The inner end of eachlatch 30 terminates in a-handle 32, and between the ends of each latch a locking-shoulder 33 is formed. Preferably the outer faces of the spring-latches 30 between the locking-shoulders and the ribs 23 are more or less inclined or eoncaved, as is also shown in' Fig. 2.

The locking-ring C, heretofore referred to,

is adapted to slide on the jaws of the female section A, and the inner face 34 of the said locking-ring is inclined or is rendered conical to conform to the exterior conical surfaces 21 of the said jaws, as is illustrated also in Fig. 2, andat the top and bottom of the said locklug-ring C a recess 3-5,is made in'the inner edge of the said locking-ring, so that when the locking-ring is carried over the exterior conical surfaces 21 ofthe jaws a and a the ring binds the said jaws together and the spring-latches 30 fly outward V at their handle ends until their locking-shoulders 33 engage with the end walls of the aforesaid recesses 35, as is shown in Fig. 2. v

In order that the locking-ring C shall not turn on the jaws a and a, lugs 36 from the inner face of the ring enter the grooves 28',"

formed in the exterior of the jaws, as is shown in Figs. 1 and 5.

In the operation of the coupling to effect a union between the two sections A and B the locking-ring C of the female section A is released from the spring-latches 30 and is slipped back, allowing the jaws a and a to separate, whereupon the -maie section B is introduced between the jaws of the female section and is forced inward until the inner end of the body of the male section B engages with thecushion 27 in the female section A, and the inner flange 24 of the female section enters the space 15 between the collars or offsets 13 and 14 on the male section, as is shown in Fig. 2. The locking-ring is then forced over the outer conical or inclined surfaces of the jaws a and a until the shoulders 33 of the spring-latches 3O entering the recesses 35 in the locking-ring hold it in position and force the jaws a and a to a close connection one with the other and the inner conical or inclined faces 22 of the jaws in engagement with the inclined or conical projection or collar 14 from the body 10 of the male section B, causing the inner flanges 24 on the jaws of the female section A to be locked in the recess 15 ofthe male section, thereby effecting a complete union between the two sections A and B.

Whenever the two sections A and B are to be uncoupled, it is simply necessary to press the handle end of the spring-latches 3O inward until they release the locking-ring G, whereupon the ring is slipped back toward the hinges 20 for the jaws, permitting the jaws a and a to separate, and upon said separation the male section B may be quickly withdrawn from the female section A.

Teats orlugs 37 are formed upon the lockingring U to be engaged by a spanner or equivalent tool, should such be employed to assist in locating or displacing the ring.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In hose, rod and pipe couplings, a female section having receiving jaws hinged for movement to and from each other, the said jaws having interior locking-flanges anda lockingring adapted in one position to close the jaws, a male section having a body portion to enter the space between said jaws of the female section, and an exterior recess to receive the locking-flanges of the said female section, said jaw-section of the coupling having parallel sides at its hinged end and being conically enlarged at its forward end within the clampingring, the opening between said jaws near their forwa'rdends being also correspondingly en' larged conically, and the rear' end of'the male member of thecoupling being comically enlarged to snugly fit said internal conical enlargement near the outer end of the jaws, said locking-ring also having an inclined bore to fit the inclined face of the jaws, as'described.
